Final answer:
The statement is false. An O-ring seal should be exposed to oil or other engine fluids. (option B)
Step-by-step explanation:
O-ring seals serve as critical components in engines and machinery, providing a seal to prevent leaks and ensure proper functioning. However, these seals are not designed to be indiscriminately exposed to oil or other engine fluids. The choice of O-ring material is crucial, and it should be compatible with the specific fluids it will encounter.
Exposure to incompatible fluids can lead to chemical degradation, swelling, or deterioration of the O-ring material. This compromises its integrity, potentially resulting in leaks and reduced effectiveness. Therefore, it is essential to choose O-ring seals that are specifically designed and rated for compatibility with the intended fluids in a given application.
The statement is false. O-ring seals should not be exposed to oil or other engine fluids without consideration of material compatibility, and it is important to follow manufacturer guidelines to ensure the proper functioning and longevity of the seals in the intended environment.
